Cetirizine HCl is categorized under a class of drugs known as antihistamines. As such, it is used to reduce histamine, the natural chemical that is present in the human body. When Cetirizine HCl is administered to a patient, it stops running noses, itching, sneezing and helps reduce pain that might be caused by such symptoms.
Doctors also use Cetirizine HCl in the treatment of swelling and itching that are as a result of hives. Once Cetirizine HCl has been given to a patient, it works by halting histamine production, thus reducing sneezing, having a running nose, and watery eyes.
Because Cetirizine HCl may cause reactions such as impairing an individual’s thinking, caution should be exercised when administering it to patients such as drivers or security guards who need to be alert.
